This website documents the building of a computer based on the Z-80 microprocessor. The intentions of this was to have fun and learn. The project starts simple with only some ICs in a test circuit on breadboards and ends with a complete single-board computer, with ROM, RAM, I/O and storage. A minimum requirement was that it should be capable of running CP/M and being accessible through a serial interface (RS-232).

I have not yet ported any operating system to the computer, but when I do, I will post it here. Same goes with the technical documentation and other interesting things.
